The chemical characteristics of groundwater of Purulia district of West Bengal were studied to evaluate the major ion chemistry and suitability of water for domestic and irrigation uses. Groundwater samples of 60 locations were collected and analysed for pH, EC, TDS, F- , Cl- , HCO3 - , NO3 - , SO4 2- , Ca2+, Mg2+, Na+ and K+. The cation concentrations indicate that among the cations only K+ concentrations in 15% of sampling location exceed the WHO limit for drinking water. In case of anions 1.67%, 11.67% and 21.67% of the sample locations exceed the limit for Cl- , F- and NO3 - respectively. Based on US salinity diagram, 50% samples fall in the field of C2S1 while 40% and 10% samples fall in the field of C3S1 and C1S1, respectively. The analytical data plotted PI against total concentration shows that 68.33% of the water samples fall in Class–I and 15% in Class–II in the Doneen’s chart implying that the water is of good quality for irrigation purposes with 75% or more of maximum permeability. However, 16.67% groundwater samples belong to Class–III, that is unsuitable category. In the analysed groundwater samples 9 samples have MH >50, that is harmful and unsuitable for irrigation use.
